The Rimuru Sword in Sailor Piece is one of the strongest late-game weapons, offering powerful skills, scaling damage, and advanced progression upgrades.
Overview
The Rimuru Sword Sailor Piece guide focuses on unlocking the weapon, defeating the Rimuru Boss, and collecting rare materials from Slime Island. This weapon is designed for players who want consistent damage output and strong boss-clearing ability. The progression includes crafting requirements, special skill unlock conditions, and Blessing upgrades that increase combat efficiency. Farming preparation and boss repetition are required to complete the full upgrade path. Players who follow an organized farming route can unlock the sword faster and maximize its full potential in both raids and grinding sessions.
How to Unlock Rimuru Sword in Sailor Piece
To unlock the Rimuru Sword Sailor Piece, you must travel to Slime Island and locate the Rimuru NPC vendor. Before purchasing the weapon, you must obtain the Demon Lord title, which drops from the Rimuru Boss after successful defeat. This requirement ensures that only prepared players with enough combat strength can access the weapon. The process involves repeated boss farming, material collection, and resource management. Players should prepare high-damage builds and healing items before starting the unlock process.
Rimuru Sword Cost and Required Materials
| Requirement | Amount |
|---|---|
| Money | 30,000,000 |
| Gems | 20,000 |
| Slime Core | 1 |
| Slime Remnants | 3 |
| Tempest Seals | 6 |
| Sage Pulses | 9 |
These materials are considered high-tier crafting resources, and most of them require boss farming or elite enemy drops. Players should prioritize collecting currency first, then focus on rare boss drops. Efficient farming routes reduce the total grind time significantly. Strong area-of-effect attacks help clear mobs faster and increase drop efficiency.
How to Summon the Rimuru Boss
To fight the Rimuru Boss, you must craft a Slime Key using Slime Shards at the Slime Key Crafter NPC. Slime Shards are dropped by Slime Warriors on Slime Island. Farming these enemies repeatedly is the fastest way to collect keys and start boss encounters. Players who maintain a steady supply of keys can complete weapon requirements faster and reduce downtime between fights.
Unlocking the Rimuru Sword F Move Ability
The Rimuru Sword F Move Sailor Piece is a powerful special ability that provides a 30% Damage Boost when activated. This skill significantly increases boss damage output and improves farming speed. Unlocking this ability requires completing a series of combat challenges assigned by the Rimuru Master NPC. These tasks are designed to test endurance, consistency, and combat readiness.
| Quest Step | Requirement |
|---|---|
| Quest 1 | Defeat the Rimuru Boss 15 times (Hard or Extreme mode) |
| Quest 2 | Have the Slime Race equipped |
| Quest 3 | Defeat 10,000 NPCs |
Completing these objectives unlocks the full combat potential of the weapon. Players should focus on consistent grinding sessions rather than short farming bursts. Tracking progress helps maintain efficiency and ensures steady progression toward the final skill unlock.
